As a reminder, Port 1 and Port 2 on the BB are ONLY used to connect the MFDBB
Keyboard(s). You can ONLY use port 3 and port 4 to connect Ethernet cables to the
DRS, HUB101, DFF1, and other Ethernet devices.
On port 1 and 2 (reserved for the Keyboard), leave the DIP switch to OFF as the BB
keyboard (MCU001) does not need the power synchronization signal.
DFF1/DFF3
The DFF1 has DIP switches that need to be set up differently if you use a regular hub or
the Furuno HUB101 (with Power Synchronization).
For the DFF1:
- Regular HUB (no Power Synch.) = Dip switches are “Down-Up-Up-Down”
- HUB101 (Power Synch.)= DIP switches are all UP
For the DFF3:
- Regular HUB (no Power Synch.) = DIP switch 1 and 2 are set to ON
- HUB101 (Power Synch.)= DIP Switch 1 and 2 are set to OFF
5.3. Heading Input
If you connect a heading sensor to NavNet3D (using one of the NMEA0183 ports), the
heading refresh rate needs to be 100ms (10 times per second = 10Hz or faster).
You can check the heading refresh rate using the port monitor of the MFD (in the
Installation Wizard). To check the refresh rate, Clear the page and immediately start to
count how many seconds are required to fill up the page. Count the number of HDG
sentence and divide it by the number of seconds. This will give you an approximation of
the refresh rate:
Note: Heading data from a NMEA2000 source/sensor will always be at the correct
refresh speed for the DRS ARPA function
